System.Runtime.InteropServices.COMException

Hi,

I am using a VB6 dll in my asp.net application.

When I call a function of that dll, I get the following error:

System.Runtime.InteropServices.COMExceptionType mismatch.

The function I am calling expects a String, and I am passing in a String.

Here is the function call:

format.ProperCase(rs("Fname"))

Please help!

try

format.ProperCase(rs.Fields("Fname").Value.ToString() )

Thank you. Do I have to do this every time now? I am converting a classic ASP page to .NET and I make this function call a lot passing in recordset fields.

System.Runtime.InteropServices.COMException - Catastrophic Exception

I'm trying to generate excel sheet using SpeedGen COM object.
I'm getting 'Catastrophic exception,Error code : 2147418113' when i
try to access methods and properties of XLSpeedGen class in
C#.Possible reasons as told on the forums are memory leaks and open
resources.I've closed all the database resources like ,connection and
data-reader objects,but that doesn't seem to provide any help.
Can anybody provide me with a solution to this problem?
An early reply would be appreciated.

Regards,
-Ritu.1) Try to activate the COM object via vbs file to check if he registered
properly.

2) Use tlbimp to generate .net wrapper class and reference to this
class.

3) Add Impersonate=true to the web.config. Use the user and password
attributes to set them with user that got the right privilege.

You'll have to look for a free component to do this - I don't know of one...

However, Aspose will do everything you require...

Hi..

Thank you very much for the reply.. But I couldn't get much help from that.

Thanks

Hi,

In that case, try posting the code which you feel causes the error.

Suprotim.

Hi venkatzeus,

According to MSDN, if the HRESULT is a custom result or if it is unknown to the runtime, the runtime passes a genericCOMException to the client. TheErrorCode property of theCOMException contains the HRESULT value. You can use catch(ComException ex) to catch this type of exception.

http://msdn2.microsoft.com/en-us/library/system.runtime.interopservices.comexception(VS.71).aspx

Hope it helps.

HI..

I searched in google and found out this:

http://support.microsoft.com/kb/232282

It says, it is a Generic COM Error Codes. How to catch these generic COM Error codes and provide more meaningful messages to the end user.

Thanks

System.Runtime.InteropServices.COMException: Class not registered

Hello,
I'm trying to develop an ASP.NET application that uses a third-party COM
dll. I've added a reference to the dll in the web app project along with
adding a "using" directive in the code-behind (referencing the COM
namespace). Every time I try and run the application and call methods on th
e
COM object, I get the following error:
System.Runtime.InteropServices.COMException: Class not registered
I've successfully registered the dll using regsvr32 and added
the AspCompat="true" directive on the Page, but doesn't seem to help.
I'd really appreciate any suggestions on how to remedy this problem.

System.Runtime.InteropServices.COMException: Operation is not allowed in this context

I just thought I would ask about this error, since I have found no
references to it on the web elsewhere.
I have a COM object from regular ASP, written for an older app that my
business needs to use, that I need to use in ASP.NET. The error
occurs here:
object obj = "test";
String testVal = (String)obj;
OldASPClass pickup = new OldDLL_dotnetproxy.OldASPClass();
pickup.MyFunc(testVal, testVal, testVal);
Somehow I ended up in a situation where it seems everything I do is
for the first time. So just as an FYI, I am an ASP.NET newbee. Does
anyone know what is going on here?On Jul 4, 4:25 pm, Dave <onlinef...@.gmail.com> wrote:

I forgot to mention that the data types in this proxy function look
like this:
object OldASPClass.MyFunc(object x, object y, object z)
I'm just trying to pass the correct data types to this function to get
this to work.

FYI, I figured it out. It was an error specific to the function
inside the DLL having to do with my input strings being formatted in a
way it didn't like.

You need to post the code you are using plus the full error message. I
received this type of error while trying to use query AD using
DirectoryServices and the authentication/impersonation settings in my
web.config were set to a system account that didn't have rights.
